I'm in the middle of James Clavell's "Shogun" and I'm deeply interested in learning more about the real-life events the novel is based on, as well as learning just how accurate his portrayal of feudal Japan is.

What was the Japanese culture truly like?

How accurate does he show the Japanese views on life, duty, loyalty, death, etc.?

Who were the real-life individuals that the characters in the book were based on?

Thanks!
